7、en she put on color-blind corrective glasses was green the vibrancy （活力） of the grass and tree and later, the brilliance of red in stop signs and flowers. Valoy says its unbelievable and she has struggled with certain topics, especially the painting class in school and she would even paint the ocean

8、 purple before that.Valoy wasnt diagnosed with red-green color blindness until the fourth grade. “For the past 17 years, Ive lived in a black and white movie,” the recent Louis E. Dieruff High School graduate says. But not anymore. The transformative moment all started with a public speaking class V

9、aloy took. After she made an informative speech about growing up with her color deficiency （缺陷）, her teacher, Sandy Kile, was inspired to teach the class a more important life lesson.Kile made a suggestion that the class should reach out to companies that produced corrective glasses to see if they w

10、ould donate a pair to Valoy. While Kile encouraged Valoy to write a description of living in a world with mostly shades of grey and brown, her classmates wrote accompanying statements about why she needed the glasses. “I didnt expect much for that,” Valoy says. “Professor Kile truly believed it was

11、going to happen but we were not sure.”It wasnt so surprising when the first company turned down their request. Then, the class received reply from the founder of Pilestone Inc., offering Valoy and six other commumity members his glasses for free. “We started this business by trying to make some diff

12、erence to people,” founder Ben Zhuang says.Valoy is grateful to Kile and her classmates for their efforts.

The challenge of keeping your body alive seems impossible, but some scientists are working on an alternative. They want to create a digital copy of your “sel

16、f” and keep that copy “alive” long after your physical body has stopped functioning.In effect, their plan is to clone a person electronically.Unlike ordinary physical clones-which have identical features as their parents, but which are independent organisms, each with a different conscious self-your

17、 electronic clone would believe itself to be you.One plan relies on the development of nanotechnology（纳米技术）. Ray Kurzweil, a leading futurist, predicts that within two or three decades we will have tiny transmitters that can be injected into the brain. Once there they would line up alongside neurons

18、 and monitor the details of the brains activity. They would then be able to transmit that information to receivers inside a special helmet, allowing us to map the brain.As a further step, Kurzweil foresees using these tiny transmitters to connect you to a world of virtual reality. With the transmitt

19、ers in place, you could think your way onto the Internet. Instead of seeing pictures on a screen, you would see them in your mind. Rather than send emails to your friends, you could meet them on some virtual tropical beach and exchange messages in “virtual person”.For a futurist like Ray, this would

20、 be heaven, a virtual heaven. Once you upload the brain onto the Internet and log on to that virtual world, your body can be left to decompose（腐烂） while your virtual self can play games for as long as you wish.However, there is still a problem. To exist on the net, your virtual self will have to liv

21、e on the computer of a web-hosting company. These companies want to be paid real money, or they will delete your “self” and sell the space to someone else. With your body long gone, how will you pay?8What do the scientists intend to do?ATo clone an ordinary person. BTo create a digital copy of a per

22、son.CTo making a man live longer. DTo produce independent organisms.9What might happen once you upload your brain onto the Internet?AYou can map the brain. BYou can play computer games.CYou can keep your virtual self alive. DYou can become conscious.10What does “heaven” refer to in this passage?AThe

23、 deepest part of their imagination. BSomewhere high above the atmosphere.CThe place of God and external happiness. DThe virtual world on the Internet.11What benefit may digital technologies bring according to the author?AExtending your “existence”. BEventually replacing physical human beings.CEnrich

24、ing your lives with more spare time. DLengthening your physical body. Every year. the Joint Mathomatics Meeting brings more than 5,000 math lovers together. Its the largest math meeting in the world. In January 2019, mathematicians flew to the meeting in Baltimore, Md., to learn about new ideas and

25、talk about their work. Many even came to admire the latest in mathematical art.The meeting included an entire art exhibition. Visitors felt amazed at sculptures made from metal, wood and folded paper. One was based on a supersized Rubiks cube. Many like triangles, were arranged in strange and surpri

26、sing sizes and colors. The collection also included drawings and paintings inspired by the study of numbers, curves （曲线） and patterns.Art and math may seem like a strange pairing. People usually experience art through their senses. They see a painting or listen to music. If this art moves them, they

27、 will have an emotional response. Working at math problems is usually viewed as something you think about-not feel. But connections between the two fields reach far back in time. Sculptors and architects in some ancient civilizations included numbers and math ideas into their works.Henry Segerman is

28、 a mathematician and artist. When he was in high school, in England, he was good at math and art. But he had to choose. “I went in the math direction back then,” he says. He thought it difficult to succeed as an artist.Still, Segermans math studies led him into the visual areas of math, such as geom

29、etry. In 2015, Segerman and some math art friends created a virtual-reality artwork. Participants can put on a pair of VR goggles to float around and through four-dimensional shapes. Art makes it possible to interact （互动） with these shapes, which would be impossible to create in our three-dimensiona

30、l world. As beautiful as it is to see, Segermans work also offers a new view on mathematical ideas.12What distinguishes the exhibits at the meeting?AThey are art works with high technology. BThey reflect the long history of math.CThey are made based on math ideas. DThey turn visual art into specific

31、 math.13What does the underlined sentence in paragraph 3 mean?AThey seem extremely hard to appreciate.BTheyre experienced in different ways.CTheyve been separated since ancient times.DThey fail to bring about peoples responses.14What can we learn from Henry Segermans story?AMath learning promotes the creation of art. BMath makes art easier to understand.CMath is actually the origin of fine art. DOne cant easily succeed in math.15What is the main idea of the text?AReal artists will stand the test of math. BMath and art turns out a great combination.CModern artists turn i
